Hey, guys. Today we're gonna be taking a look at and installing the Roush High Flow Lower Grille for 2018 GT and EcoBoost Mustangs. This is gonna be a good option for really anyone looking for a lower grille for their 2018 Mustang. It offers a big change in style and it also improves airflow. It's gonna improve airflow because it has a larger opening here than your factory grille does and that makes it a very viable option for those high performance 2018s out there that are looking to improve cooling or maybe even get some air to an intercooler. This is made from a TPO material so it's lightweight but also strong and durable. And it has a grainy black textured finish, which means that it's gonna match your other factory trim.Now this does require the Roush Chin Spoiler and Wheel Shroud Kit in order to be installed. So just keep that in mind. The lower grille costs about $240 and as far as the install, I'll call it a two out of three wrenches in the difficulty meter because you do have to pull the front fascia, and you will need to install this chin spoiler, which does mean some drilling and a little bit of modification. But with all that being said, let's go ahead and show you how to get this on the car. All right guys, since we are installing the lower grille paired with the chin spoiler and a wheel shroud kit, we're gonna go ahead and remove both front wheels first as our first step. All right guys, the next step's gonna be to remove some of the push pins that are in our wheel liner here. So we're gonna go ahead and use a priy tool and remove some of the push pins. There are eight push pins on our rad cover that we're gonna take out now. All right, after those are removed, we can go ahead and lift this off. There are six eight millimeter bolts in the top of the bumper here, we'll go ahead undo those. And then at the end, there are two seven thirty-seconds small bolts at the very edges and we'll go ahead and undo those too.All right guys, there are 2 10 millimeter nuts then that we're gonna undo next that are holding the bumper in place. They're separated by a Christmas tree. There are a couple of different ways that you can get to them. You can get to them through the wheel well or you can go through the top in between the frame like I'm doing now. It's really gonna be up to you. So we'll remove the nuts for now and we'll leave the Christmas tree clips clipped in until we go underneath the car and remove our splash shield. All right guys, now we're gonna remove the splash shield from underneath the car. There are two push pins, we'll grab those first and then you have a couple seven millimeter bolts to get as well. All right, now we're gonna disconnect our turn signal. So we'll go ahead and find our electrical connection. There's a tab on the top, push down on the tab and disconnect. We'll do the same thing for both sides. All right guys, now you're ready to remove your bumper. I have a second set of hands. I have Joe here helping me, it's probably gonna be easier if you guys have someone helping you as well. What you're gonna want to do, is you're gonna want to pull down the corner. You have that Christmas tree clip holding this in place. All right and now you have dowels on the front, so you lift off the dowels in the front and then set your bumper somewhere safe.All right guys, now we're gonna remove the 3 70 millimeter nuts that are holding each turn signal and fog light in place. All right, so now we can remove the assembly. All right guys, now we need to remove this plastic energy absorber from the bumper. So there are six tabs holding this in place. So we'll go ahead pry up on the tabs and remove this. All right so the next step is gonna be to remove the lower grille which is also held in by the same type of tabs. Now I do have Joe helping me here with this just to make it go a little bit quicker. So I'm gonna pry back on the tab. All right guys, now we're gonna remove the front chin spoiler from the fascia. There are six push pins, three on each side, and then there're also seven millimeter nuts that are holding the chin spoiler in place. All right guys, so at this point, we are getting our lower grille ready for install into our front fascia. We have five strips of 3M tape here. We are gonna use the 3M tape. I do have the tab bent over. I am gonna put all five pieces on the bottom of the lower grille here. You need to make sure that the tab is facing outward though so once we install this we'll be able to pull the tab and have the adhesive side stick to the bottom over front fascia. So we're gonna peel the white backing off. You always want to make sure that you have clean surfaces when you're applying 3M tape, that means both on the back of this grille and on the lower front facsia. All right, guys, now we're gonna clip the grille into place. This is a little bit tricky. We're gonna do it from the front, we have to go in at an angle and I still have Joe here helping me. All right, so basically we're using the plastic tabs that are on the bumper and we're getting them in place on the top of the grille now. All right, now we're gonna pull the backing off the 3M tape and what you want to do is you want to make sure that you're holding the lower fascia onto your grille here, so you have a good adhesion between the 3M tape.All right guys, so at this point Joe and I have the lower front grille in place. But in order to finish the install of the lower grille, you need to install the Roush Chin Spoiler. These parts go hand in hand. So Joe and I have a few more things we have to wrap up on the chin spoiler before we get the front fascia back on the car. All right guys, so you get your front fascia back on bolted down into place, then you get your canards on either side. And the last thing that you'll do is a graphic that Roush gives you for out front. Okay guys, with the front fascia hanging, our bracketry all tightened down and completely taken care of, we're gonna go ahead reconnect our fog lights and turn signals and then get the belly pan in place. All right guys, that's gonna wrap up this review and install. Keep in mind that you can always check this out more online right here at americanmuscle.com.
